Configuring Protocol Based Vlan - ZyXEL Communications GS1920 series User Manual

Chapter 9 VLAN
For example, port 1, 2, 3 and 4 belong to static VLAN 100, and port 4, 5, 6, 7 belong to static VLAN
120. You configure a protocol based VLAN A with priority 3 for ARP traffic received on port 1, 2 and
3. You also have a protocol based VLAN B with priority 2 for Apple Talk traffic received on port 6 and
7. All upstream ARP traffic from port 1, 2 and 3 will be grouped together, and all upstream Apple
Talk traffic from port 6 and 7 will be in another group and have higher priority than ARP traffic,
when they go through the uplink port to a backbone switch C.
